Project information

The Princes Highway is an important urban arterial road, and forms part of the A1 road corridor. The A1 connects the south coast of NSW and Wollongong to Sydney. It also provides access to major roads including the M5 Motorway, A3 King Georges Road, A36 Princes Highway (city) and M1 Pacific Highway.

Road users are currently experiencing congestion due to high volumes of vehicles travelling along the corridor and turning right at the intersections of Acacia Road, Oak Road and Kingsway. In addition, there are currently high volumes of vehicles travelling in both directions on President Avenue and the Princes Highway. These delays are caused by turning vehicles blocking through traffic.

This project aims to ease congestion at these intersections and improve journey reliability for all road users.

Benefits include:

  • improved operation of Princes Highway along the corridor and at the intersections with Acacia Road, Oak Road, Kingsway and President Avenue
  • improved safety at the intersections, with a reduction in the number of rear-end crashes and crashes involving motorists changing lanes
  • reduced traffic delays and a better flow of traffic for motorists at all points along the corridor.

Since work started in April 2018 we have:

  • started work to upgrade the central median on Princes Highway
  • moved services and started to relocate utilities on Princes Highway and President Avenue
  • completed intersection improvements at President Avenue and Acacia Road, including relocating the lights at President Avenue and extending the intersection turning lanes
  • completed a new left-turn slipway from Princes Highway onto Kingsway
  • continued construction of a new retaining wall on the northern side of Princes Highway between Acacia Road and Oak Road.
  • Night works will continue on Princes Highway.
  • Traffic signal upgrades and installation will continue in stages.
  • Construction of an additional right turn lane from Princes Highway northbound onto Kingsway.
  • Construction of the access road will continue
  • Completion of the retaining wall along Princes Highway.
  • Construction of a new southbound left turn lane from Oak Road onto Princes Highway.

Roads and Maritime invited feedback on the proposal in May and June.2017. A total of 220 submissions were received in response to the display of the Review of Environmental Factors (REF). This included one submission from the Sutherland Shire Council, and 219 submissions from the community. Of the total submissions, 19 were in support of the proposal, two opposed the proposal, 142 did not state a preference on the proposal, and 56 were not relevant to this proposal (i.e. concerned other proposals of the Gateway to the South Pinch Point Program, or more general road network improvements).
